Vinegar works as a safe, non-toxic homemade grass killer. Just put it in a spray bottle and spray the areas where you want to kill the grass. For grass that is growing in the cracks in a sidewalk or driveway, you can burn it out using a torch.

Boiling water will kill grass and weeds, but this works best for spot treatment -- you would need a lot of boiling water to kill a lawn! Otherwise, grass can be killed by mechanical means such as covering it with plastic sheeting and allowing it to remain for several months. This is a non-toxic solution.

Usually vinegar, hot water and dish soap are used as homemade grass killers. However, it would be fine when neem oil extracted from neem tree is sprayed on the roots of the grass.

Vinegar is great for killing weeds like dandelions but will kill grass as well. Many store brought weed killers contain similar compounds like propanoic acid as opposed to the ethanoic acid found in vinegar.

Regular table salt can be poured on the area where you want to kill the grass, but you have to pile it on. Vinegar is also a good grass killer, you can pour it on the area or our can apply it directly to the grass you want to kill.

Will the vinegar solution leave marks on my brick pavers? I have grass that sprouted between the cracks after the lawn was re-seeded. I use a weed torch each week but the grass keeps growing back.
